Henry Shuttleworth Martin-type Microscope

4.99

An unusual intermediate form depicting the transition between Benjamin Martin’s Universal, the Adams Improved and the Jones Most Improved microscopes by Henry Raines Shuttleworth with a compass joint uniting the pillar nearly at the upper end of the limb (1782) and the instrument and its accessories packed in a box rather than a pyramidal case. The cruciform Ayscough stage has fittings for both a bull’s-eye and stage forceps. Most peculiar is the base with folding cabriolet legs.  The stage and mirror travel along an internal rack-work and pinion driven by thumb-wheels. The arm hold the optical tube is provided with a special screw that provides semi-aquatic movement in an arc and lenses can be mounted beneath the arm to permit use as a simple microscope.
